Answer:
a. C = 12x + 110; b. $290
Step-by-step explanation:
a. The polynomial
Let L = cost of flip-flops
and S = cost of sandals
Then
C = L + S
= 40 + 4x + 70 + 8x
= 12x + 110
b. The cost
C = 12 × 15 + 110
= 180 + 110
= $290
The cost of making 15 flip-flops and 15 sandals is $290.
Ok so I’m assuming the question is how the tall is we need to find the Angle of the sun so
Student : 175
Shadow: 2.3
Hypotenuse: 175.0151136
Using -cos(175/175.0151136) we find the
Suns angle: .753 Above him/her
Our tree’s shadow:8.2
Using the suns angle we use cos(x
Answer:
1 out of every 3 races could be won by Rachelle
Step-by-step explanation:
12,571.4286 you subtract 1000 from the total, and divide by 7.
If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint
i.e. the whole wall
